TYPEWRITING MACHINE.

Application filed July 10, 1923. Serial No. 650,601.

To all whom it may concern:

Be it known that I, CLARENCE M. Cnnws, a citizen of the United,States, residing in Brooklyn Borough, in the county of Kings,

city and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to carbon-carrying means in typewriting machines whereby a number of superimposed'webs or continu ous work-sheets may be fed through the machine, for continuous billing or other work. i i

Printed forms are usually repeated upon the plies of web, and several of these worksheets are superimposed and fed into the machine, where they may be interleaved with carbon-sheets preparatory to typing. A small amount of work would not warrant the purchase of a machine built especially for continuous billing, and therefore one object of ,the invention is to provide means that may be used with an ordinary typewriting machine.

Another object of the invention is to provide means whereby the carbon-sheets may be transferred from a completed form to the next succeeding form to be typed by means of stripping, as in the fantlie platen of the typewriter.

In securing these ends, a back or base, preferably made of cardboard or other tough, though flexible, material, has-formed therein a plurality of transverse slots,

which divide a portion of the base into a plurality ofitransverse strips to which are fastened a plurality of carbon-sheets of any desired length to suit the length of the worksheet sections. The back of the pack is also furnished, preferably near the cot- 11ers of its trailing edge, witlrhooking or stopping members. The leading ends of the webs may be threaded through the ,slots, to interleave them with the carbon-sheets, and be brought forward until they re ister with the leading end of'the flexible ack. The leadingend of the back thus forms a gage for the work-sheets, which will bring the carbon-sheets with their leading ends in position to transfer matter that is t ped line of the first fiirm.

The combined pack t us formed is fed into the machine in the usual manner of feeding old machine, without the necessity of displacing an ordinar work-sheet, and is advanced by means of t e ordinary feed-roll mechanism, until its leading edge has assed beneath a Web-severing knife, and t e first line of writing on the first form appears at the printing point. The matter to be transit with the fingers, unti the retaining hooks on thecarbompack become fastened over the edge of the rear paper-table of the machineyin, which position they will revent any further forward movementof t e earbon-pack itself.

The feed-rolls bein ends of the work-s eets alone may grasped by the fingers, and ulled forward beyond the leading end of the back of the carbon-pack, strip ing the carbons from the web-plies, until t e line of separation be tween the first and second printed forms registers with the leading edge of the back of the carbon-pack. This operation of the web; relatively to the web-rider strips the carbon-sheets from the first form and places them in position with their leadingends to transfer matter, typed upon the first writing' line of the second form. It will be observed, in case"- the forms are of such a length as would make it uncomfortable to withdraw them during this 0 eration by grasping the leading ,ends 0 the workreleased, the leadin sheets with the fingers of only ,one hand,

*the hooking or stopping members holding the trailing end of the carbon-pack or web- 'rider stationary without the necessity of furtheriholding it with one hand. There being preferabl a hook or stop on each side of the trailing end of the carbon-pack, they will also prevent skewing of the pack or rider when the feed-rolls are released during the stri ping operation.

The feed-r0 may now be thrown on again, and both the web-rider or carbonpack and the work-sheets may be back-fed together until the line of separation mentioned is opposite the cutting edge of the 110 pack and advancing scribed to the first form is now typed v knife, in which position the first form is ready to be torn off, and the second form is in position to be typed upon, with the first writing line of the latter at the printing point. from the work-sheets, the entire operation ma be re eated. 1

t will e noted that ty ing upon one form is completed, and another form interleaved with carbons, and brought with its first writing line to the rinting point, ready to be typed upon, wit out displacing the platen at any point in the operation, and without removing the work-sheets from the machine.

It will also be noticed that the machine in which this has been accomplished is an ordinary-typewriter, to which has been added only a standard collating table which bears a web-severing knife, accessories that require onl a moment, and no changing of the mac ine, to fasten in lace.

In other'words, the use of he invention with an ordinary typewriter, fitted withthe accessories mentioned, enables a typist to accomplish the same work that is usually done u on a much more expensive and complicate machine, with as much ease and 1 speed as could be had with that machine.

Other features and advantages will hereinafter appear. 1

In the accompanying drawings,

Figure 1 is a perspective view of the in.- vention as it appears when bent. around the platen of a typewriter, and shows the manner in which carbon-sheets, are fastened to members between slots which are formed in the back of the pack to admit continuous work-sheets. i

Figure 2 is a sectional view of parts of the carriage of a t pewriting machine, and shows the carbonts interleaved between the leading ends of the continuous work sheets which have been fed through 'the machine, and typed upon, until the first printed form thereon has been completed.

Figure 3- is a sectional view, similar to Figure 2, and shows the combined pack advanced through the machine to the point.

where the transfer of carbon-sheets is about to take place.

Figure! is a sectional view, similar. to Fi ure 3, except that it shows the leading ends of the work-sheets advanced to strip the carbons from the first form and to bring them into position for the second form.

A platen 5, rotated by the ordinary linespacing mechanism 6 or platen-knob 7, is mounted in a carriage 8, to movetransverely.of the typewriter on a rail 9, supported in the frame 10 of a typewriting machine.

7 The usual feed-rolls 11 and 12 eo-operate with. the laten 5 in feeding work-sheets through t e machine, which is furnished with type-bars 13. The carriage 8 is provided After severing the first form.

fposition shown in Figu with a rear paper-table 14, on which are mounted two paper-guides 15 of the usual sort.

There may be mounted on top of the carriage 8, by means of brackets 16 and a crossmember 17, an ordina collating table 18, which may be furnishe with an adjustable web-sever ng knife 19. A. carbon-pack or carrier 20 is preferably made with a stiff back-member 21, in which may be formed a plurality of transverse slots 22 separated from one another b members 23, to which may be fastened car on-sheets 24. The back 21 is a web-rider, as it is shifted upon the web at intervals, and it is preferably furnished near the corners of its trailing end with hooking or stoppin members 25.

In operation, a num er of continuous work-sheets 26, which may have work-sheet sections indicated thereon, may be superimposed to form a pack 26. With the carhon-pack 20 laid fiat, the leading edges of the is advanced, by employing the line-spacing mechanism 6 or platen-knob 7, to bring the first writing line of the first work-sheet section to the printing point. The matter to be typed upon the first work-sheet section is now transposed.

As this typing operation progresses, the leading edge of the combinedpack 27 is guided beneath the web-severing knife 19, and over the collating table 18. The completion of the typing operation mentioned will bring the combined pack 27 to the position shown in Figure 2.

The combined pack 27 is now advanced, either by rotating the platen by means of the platen-knob 7, or by releasing the feed-rolls no 11 and 12 and grasping the leading edge of the combined pack 27 to draw it forward with the fingers, until the hooking or stopping members 25 engage the edge of the rear paper-table 14, which will bring it to the 115 re 3. N

If the feed-rolls 11 and 12 were not released to accomplish the operation just finished. the must now be released so that the leading Yen s of the work-sheets 26. alone may be 129 1 pro er position between the continuous when the line of wor she'ets .26 at the ,second or succeeding work-sheet section, where they will be in position to transfermatter typed upon the .5 second Work-sheet section.

l 1 The feed-rolls 11 and 12 are now thrown a on again, and the. platen fed 'in reverse linespace-direotion, by means of theplatenknob 7, until the line of separationbetween the first and second work-sheet sections is opposite the cutting edge of the knife 19. The

completed leading work-sheet section now. may-be severed from the pack; the knife 19 having been positioned. previously, so that,

paration at the bottom of i j the operation, afterthreading the carbonpack 20 with the work-sheet plies, will be exactly similar to that described above.

A paper-guide 28 may be mounted upon the type-bar segment: 13 to hold the comf 30 bined pack 27 closely adjacent to the platen 5..
